convertir le document word en pdf

Question

J'ai un RadGridView qui devrait être exporté au format doc, pdf, csv et xls. L'exportation vers doc, csv et xls fonctionne bien ... mais il y a quelque chose qui ne va pas dans l'exportation au format pdf. L'exportation des œuvres de pdf, mais les colonnes que je cache montre encore ...

Donc, je viens de penser à exporter le RadGridView en pdf par: l'exporter à mot puis le convertir en pdf ... programme

Par le chemin, voici mon code pour exporter au mot.

 
//export to doc 
private void Export_Doc(object sender, System.Windows.RoutedEventArgs e) 
{ 
    ExportDialog("doc", "Word", ExportFormat.Html); 
} 
private void ExportDialog(string extension, string selectedItem, ExportFormat format) 
{ 
    SaveFileDialog dialog = new SaveFileDialog(); 
    dialog.DefaultExt = extension; 
    dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, selectedItem); 
    dialog.FilterIndex = 1; 
    if (dialog.ShowDialog() == true) 
    { 
     using (Stream stream = dialog.OpenFile()) 
     { 
      GridViewExportOptions exportOptions = new GridViewExportOptions(); 
      exportOptions.Format = format; 
      exportOptions.ShowColumnFooters = true; 
      exportOptions.ShowColumnHeaders = true; 
      exportOptions.ShowGroupFooters = true; 

      RadGridView1.Export(stream, exportOptions); 
     } 
    } 
}

utilisant le mot via OLE Automation (Remarque: mot COM ne rentrante - assurez-vous de ne pas appeler cela simultanément à partir de différents threads):

/// <summary> 
    /// Interacts directly with Word via COM to convert a document to PDF 
    /// Must have the Microsoft enhancement installed to support Save As PDF 
    /// in the word file menu 
    /// "2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS" - SaveAsPDFandXPS.exe

    private void ExportToPDFUsingWord(object sourceDoc, string destPDF)

     finally

      //Debug("Collecting garbage"); 
      GC.Collect(); // forces the garbage collector to run and might release any references that the RCW still has 
      GC.WaitForPendingFinalizers(); 
      //Debug("Word objects finished"); 
     } 
    }

En utilisant DevExpress (ci-dessous le code fonctionne uniquement avec Format RTF - qui ne fonctionne pas nécessairement avec toutes les fonctionnalités de Word):

private void ExportToPDFUsingDevExpress(string sourceDoc, string destPDF) 
    { 
     DevExpress.XtraPrinting.PrintingSystem printingSystem1 = new DevExpress.XtraPrinting.PrintingSystem(); 
     DevExpress.XtraRichEdit.RichEditControl richEditControl1 = new DevExpress.XtraRichEdit.RichEditControl(); 
     richEditControl1.LoadDocument(sourceDoc); 
     DevExpress.XtraPrinting.PrintableComponentLink link = new DevExpress.XtraPrinting.PrintableComponentLink(printingSystem1); 
     link.Component = richEditControl1; 
     link.CreateDocument(); 
     link.PrintingSystem.ExportToPdf(destPDF); 
    }
